Tidying the Human Activity Recognition Data Set

Aim

This project aims to create a tidy data set from the raw data to facilitate Data Analysis.

Data Set

Human Activity Recognition using Smartphones Data Sets

Files

• CodeBook.md: codebook that describes the variables, data, and any transformations or work performed to clean up the data

• run_analysis.R: The script which performs the required steps to tidy the data which are:

  • Merges the training and the test sets to create one data set.
  • Extracts only the measurements on the mean and standard deviation for each measurement.
  • Uses descriptive activity names to name the activities in the data set
  • Appropriately labels the data set with descriptive variable names.
  • From the data set in step 4, creates a second, independent tidy data set with the average of each variable for each activity and each subject.

• final.txt: The tidy data set after performing the above steps
